Despite her slumber at such an early hour, the excitement of the previous day knocked Chiharu out, causing her to sleep for a full fourteen hours, Yuriko's concoction doing its work throughout the night, her burgeoning flesh expanding and filling out more and more as three gallons of enriched breast-growing soup was digested and started to course through her veins. Habitually, she had let her arms rest near her head, keeping the growing flesh from pinning them down (not that there was much room on her bed for her to rest her arms, the sides of her breasts almost to the edge prior to eating the soup). However, thanks to the amount of shock her mind had endured, her body was too fatigued and weighed down to move around during sleep, and too enraptured with what happened to keep any recollection of dreams. Yet somehow, in her head, Chiharu's subconscious noticed that the weight on her chest was getting greater, and for some reason it was spreading all over her body.
The growth started soon after she fell asleep. Within ten minutes, her stomach began to gurgle with the insane metabolic charge her body was getting from whatever the concoction contained, as growth began to riddle her body. The already enormous mounds of breast flesh began to grow at an astonishingly quick pace, visibly swelling and jiggling as they spread out on her body. The edges of her slightly flattened breasts began to grow quickly over the edges of the bed, every few minutes another inch would slowly peer over, her breasts beginning to slide slightly, teetering on the edge of falling off the side of her short Japanese cot. Continuing in every direction, her small yet still-growing nipples, hardened by the cold thunderstorm outside, began to move further down her body, the lower lobes of her breasts now covering her thick hips... which had started to absorb some of the growth for themselves, her fattened rear starting to push towards the edge of the mattress.
Small groans of straining wood and screws could be heard down the hallways (if Yuriko wasn't too busy sleeping off her own gorging) as her stomach gurgled again, the pace picking up even more as the flesh started to retreat from its natural cleavage on her chest, and started to fall the foot in distance from the cot to the cool, carpeted floor. an inch every few minutes became inches a minute as they seemed to almost explode with growth, flood gates of flesh pouring into her breasts. Finally, the teetering mams fell to the ground, separating her natural cleavage. However, because of so much growth, very little pulling on her chest occurred as her now six-inch long, four-inch wide gorged nipples pressed into the ground with hundreds of pounds of breast resting atop of them, and more piling on every second. The large sacs of flesh spread onto the ground like rising dough, covering circles almost four feet around. Thanks to them falling, her hips were relieved of the weight for a moment, their growth revealed to the air in all their thick glory, her fattened, flattened rear beginning to creep to the edges of the four-foot-wide cot. She would of lifted her hips in slight ecstasy and agony as her nipples and breasts rubbed against the rough carpet, but the weight of her rear and thighs, along with her mental fatigue, kept her from doing anything but moan in her sleep.
Then, with one loud, rapturous gurgle from her one-again 21-inch waist, the growth picked up AGAIN, her toes beginning to curl in unbridled pleasure. The once separated cleavage of her fallen breasts began to recover itself in a miraculous show of growth as her resting flesh began to pour out on the room, pressing into the sides of the cot and surrounding furniture, just as the combined weight of her appendages caused the brittle frame to collapse, the mattress falling slowly as it pressed her breasts out, sinking to the floor. Now closer to her mams, Chiharu's breasts continued to grow at a pace faster than anyone could ever expect, as if a fire hose were pumping her full of flesh. The once astonishing cleavage her breasts had created as she rest upon her cot earlier was now easily surpassed as six-foot-wide breasts piled upon her body as her fat rear now flattened the mattress it rest upon, spreading over the edges by almost a foot, her thighs beginning to press her legs apart underneath her expanding mams, dainty shins and feet curling slightly as the subconscious pleasure continued.
Chiharu's head began to roll slightly at all the feelings coursing through her now-gigantic body, her breasts surpassing any size other than meters and feet.... minutes passed as they continued to pile up, pushing seven, eight, nine... even further in diameter, their friction on the ground and growth finally allowing her engorged nips to pop free, their enormous glory revealed to the open air as she moaned audibly, two-foot long (and eight-inch wide), fat and hardened teats rest upon the ground, pushed further and further away by her growth, heading to the closed door of her slightly-large room, now occupied with thousands of pounds of breast-flesh.
With one final gurgle, the growth exploded to an incomprehensible speed for just a moment, adding another few feet to her breasts — her hips, still hidden underneath her flesh, widening as well, before the growth finally halted. Chiharu's body was riddled with wanton pleasure, her mouth slighty agape and moaning lightly, massive amounts of pleasure sensors responding to the cold air and frictioned carpet. The final mass of her body was a sight to behold.
Her large, twenty-two by seventeen foot wide room was almost without floorspace. Her gigantic breasts had stood clear of her face and arms, but were coming dangerously close to spilling onto her neck and shoulders, her breathing not nearly as labored as it should of been with so much weight pressing down on her torso. Large, three-foot nipples were protruding from abnormally small areola only a foot or two in diameter on her gigantic breasts, one shoved up against the wall just under her covered window, the other the door, the end tickling the cold bronze of her doorknob. Breast flesh spread from there, pushing against the walls, or edges of furniture, pushing a lamp over and shoving smaller items like her chair and desk up into the walls, resting slightly on her breasts. The pliant flesh squished into corners and under gaps, the only bit of walkable space being just around her arms and head, and a little at the opening to the toilet connected to her bedroom. Cleavage created by the squished breasts rose up almost seven feet above her, rippling and jiggling uncontrollably as every breath caused a slight rise and fall, a butterfly effecting causing every inch of her beautiful flesh to move in rhythm with her breath. Her body, lying underneath the literal mountain of breast, he waist began to suffer, but in relativity, it was if nothing occurred, her stomach thickening just slightly to a small potbelly of 84cm (33 inches), but still retained a slight hourglass shape as they led down to impossibly thick thighs and gigantic rear. Her thighs were pushing five feet wide each, pushing her knees apart into an almost split-like behavior, her toes curled as weight piled on her entire body, her rear spreading out another two feet beyond her thighs, tapering into incredibly cartoonishly proportioned calves, which had received none of the growth, and her dainty feet, hidden beneath thousands of pounds of her fourteen-foot wide breasts.
